IMPROvED'STRAbDLE-PIPE FOR HYDRAULIC GAS-MAINS.

Th. Schedule referred to in these Letters Patent and making part of the same. l

To all zhom 'it may concern:

Be it known that I, PETER MUNZINGER, of the city-and county of Philadelphia, and State of Pennsylvania, have invented an Improved Straddle-Pipc for Hydraulic Gas-Mains; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying sheet of drawings, and to the letters of reference marked thereon.

My improvement consists in the construction and arrangement of the` st-raddle-pipe, whereby advantages lare gained over those now in use, of which the following are a part,'viz: lA greater number of retorts can' be applied to one andthe same hydraulic main; the area of the hydraulic main is increased; an immense saving in metal-is effected, substantially as is hereinafter shown and described.

0n reference to the accompanying sheet of drawings, making part of .this specification- Figure l shows the straddle-pipe in common use for conveying the gas from the retorts to the hydraulic main;

Figure 2 is a sectioned elevation of my improved straddle-pipe;

Figure 3 is a sectioned top view of the same; and

Figure 4- is a top or plan view.

Similar letters refer to similar parts iu the several views.

Before proceeding to describe my improvement, it will be necessary to explain the stra'ddle-pipe now in common use, in order to a full realization of the dif'- ferences and advantages claimed. It is shown atvv A,

, fig. 1, ofthe accompanying sheet of drawings, in which B is the stand-pipe, which connects the retort with the'vertical pipe D of the straddlepipe,which, in turn, is communicated with the vertical pipe E (also of the straddle-pipe) on the dip-pipe F, by the transverse pipe G.

It will be readily observed that a straddle-pipe constructed as shown and described, necessitates the use of a dip-pipe,- F, which .by depending into the hydraulic main H, occupies that much of its area, which would otherwise be filled with gas, and 'as each hydraulic main has several dip-pipes, a straddle constructed to dispense withthem will eect a vast saving of mate- Its top end extends to within a convenient distance of the top oi the said exterior chamber, While its bottom end projects, and connects with the stand-pipe K from the retort. The pipe I is eccentric to the chamber J, 'thereby leaving a space, :c-y, between them for the passage of the gas. The connection with the hydraulic main L is, by means of vtle short neck or nozzle M'of the straddle-pipe, Hanging or butting air-tight against a similar opening formed in the side of the hydraulic main. v

It will thus be seen that the-use of a dip-pipe is entirelydispensed with, thereby `correspondingly increasing the area of th'e hydraulic main.

The fluid is received into the neck M, the depending diaphragm or weil' N of the chamber J, dips below its level; the gas from the retort, rises in the standpipe K, passing through the pipe I, when it is deflected by the top of the chamber J, down the space x-y, and enters the hydraulic main through the neck M. Having passed under the ,Weir N through the liquid, it cannot possibly return to the retort, unless the level 0f the inid in the lnain be permitted to sink below the bottom of the Weir.

An opening, O, isV formed in the top ofthe chamber J, for facility in cleaning. It is closed by a cap, plug, or other `suitable device, which, when clayed, makes a perfectly air-tight joint.

What I claim as' my invention, and desire to secure by Letters Patent, is-

The interior pipe I, chamber J, neck M, and the diaphragm or weir N, the whole composing the straddle-pipe H, substantially as and for the purpose shown and described.

In testimony whereof, I hereunto sign my name to this specification in presence of two subscribing witnesses.

'PETER MUN ZIN GER.
